For bar graphs only, this property sets the spacing
between bars within a group (clusters) in a side-by-side bar graph.
A larger number creates more space between bars within a group.
When this property is set to zero, there is no space between the
bars and all bars in the group will touch each other. When this
property is set to 100, bars in a group are as far apart as possible.

Syntax:

setRiserBarGroupSpacing(value);

value = getRiserBarGroupSpacing();

where:

value

Is any integer between -1 and 100. 0 is the default value.

Example:

setRiserWidth(40);
setDepthRadius(0);
setRiserBarGroupSpacing(20);

setRiserBarGroupSpacing(50);

Note:

This property
is interactive with RiserWidth. If bars are set to maximum width, space
cannot be allocated between bars within a group (that is, group
spacing works by rearranging the space available between the Risers
after the size set by RiserWidth). RiserWidth affects the amount
of space available to RiserBarGroupSpacing.

This property
affects all riser objects, it cannot be applied to an individual
series or group.
